    Abstract: An embossing and laminating machine is provided comprising a first embossing cylinder with a surface provided with a first set of protuberances and a second embossing cylinder with a surface provided with a second set of protuberances. The two embossing cylinders forming a nip. First and second pressure rollers interact with the first and the second embossing cylinders respectively. The protuberances are constructed in such a way that in the nip some of the protuberances of the first set coincide with some protuberances of the second set while other protuberances of the first set are out of phase with corresponding protuberances of the second set.

    Abstract: A process and apparatus for bonding and embossing of sheet material is disclosed. The apparatus uses a pair of rotating calender rollers which are spaced apart. Sheet material is introduced into the space between the rollers. The calender rollers are equipped with raised, discrete points which form a surface design and determine the embossing design produced on the sheet material. The calender rollers are each driven at a synchronous speed by a drive system having the capability of varying the speed of one roller for a short period of time. This change in speed causes the surface designs of both calender rollers to shift relative to one another. This results in different degrees of overlap between opposing pairs of raised points. Thus, different embossing surface patterns can be produced as the overlapping areas are adjusted while the machines are in operation. This eliminates the necessity of replacing the calender rollers when a change of embossing patterns is desired.
